Answer:
a) 55%
b) Joint Probability
c) They are not mutually exclusive
Explanation:
Part 1 of the Question
First, we determine the formula for calculating the probabilities of Yellowstone Park and the Tetons as follows
Probability of Yellow Stone = <em>p(</em>Yellowstone)= 0.5 or 50%
Probability of Tetons = <em>p(</em>Tetons)= 0.4 or 40%
Probability of Both = <em>p(</em>Both)= 0.35 or 35%
Therefore, the probability of visiting at least one by a vacationer is as follows:
p(At least One) = <em>p(</em>Yellowstone or Tetons)
= <em>p(</em>Yellowstone) + <em>p(</em>Tetons) - <em>p(</em>Both)
= 50%+40%-35%
= 0.5+0.4-0.35
= 0.55 or 55%
Part 2 of the Question
First the probability of 35% represents the possibility of a vacationer visiting the two locations, hence, it can be called the percentage of intersection between Tetons and Yellowstone. It is also referred to as joint probability
Part 3 of the Question
Once event are mutually exclusive, it means they cannot be carried out or considered together. In other words, one becomes an alternate cost for the other. This means going to Yellowstone means the vacationer cannot go to Tetons and vice versa. In this situation, the joint probability will not be possible (0%). Since, we already know that there is a joint probability of 35%, it means <u>the events are not mutually excusive</u>
Answer:
1.) Business cycle/ True
2.) True
3.) The unemployment rate declined
Total real income increase
Explanation:
Business cycle can be explained as the rise and fall in production output of goods and services in an economy. Business cycle are generally measured using the rise and fall in the gross domestic product(GDP), either nominal or adjusted for inflation. Business cycle is closely related to the economic cycle and trade cycle.
Every nation's economy fluctuates between periods of expansion and contraction. These changes are caused by levels of employment, productivity, and the total demand for and supply of the nation's goods and services. In the short-run, these changes lead to periods of expansion and recession. But in the long-run, economic growth can occur, allowing a nation to increase its potential level of output over time.
In 1950, during the experience in increase in real GDP, U.S had about 8.7% increase in growth, a declined rate of unemployment to about 4.3% with the inflation rate of 5.9% , this era was considered to be expansion and korean war.
